i'm using betty crockers devil food cake mix. i read here you need 1 mix for an 8in, 2 for a 10inch 3 mixes for a 12inch and 4mixes for a 14 inch cake. but so far ive baked the 8 and 10inch cakes and the don't look to high. am i missing something?
also if i'm baking in a 14inch cake pan, what can i use in the middle to ensure it is cooked properly throughout the cake?

please someone help!i'm sure someone knows

Add a tablespoon of meringue powder to your mix and use the bake even strips.

For the 14" use a greased cake nail to help in even baking.
HTH

thanks for helping. but can i ask why i would need to put meringue powder when ive already put 3 eggs as requested by the box? would this make the cake go higher?

Are you using round or square pans?
Are they 2" deep?
We need more information really

its a round pan and its 3inches deep.

O.k. that's part of your problem. I don't work w/3" pans but it sounds to me like the amounts of batter is about right.
What temp are you baking at? I suggest 325 degrees F. Sorry, don't know what that would be where you are.
Try using 'magic strips'....which you can make by wetting a bath towel; slightly wring out excess water so it's not dripping but still 'wet'. Wrap around the outside of the cake pan; pin together.
Oh, using meringue powder is basicly like adding another egg white. Some people feel it helps make the cake rise better
